[ANN] Sparta v1.0
by Aliaksei Syrel Sept. 12, 2016

Sept. 12, 2016

Hi I am happy to announce the release of Sparta v1.0 for Pharo 5 and Pharo 6. https://github.com/syrel/Sparta/tree/v1.0 For a moment only Linux and Mac are supported. It can be bootstrapped with the following script: Metacello new baseline: 'Sparta'; repository: 'github://syrel/sparta:v1.0/src'; load: #file:core (on linux install 32bit libgtk-2, lingtk-3 and libstdc++) (script for ubuntu http://ws.stfx.eu/IEAWCUC18BH) Sparta is an almost stateless vector graphics API for Pharo that provides bindings to the Moz2D rendering backend. Moz2D is the extracted graphical engine from Mozilla Firefox compiled as standalone shared library together with the extern C bindings required to call the engine from Pharo. - developed with the help of Iceberg <https://github.com/npasserini/iceberg> (thanks!) on Github. - integrated into travis-ci <https://travis-ci.org/syrel/Sparta> using smalltalkCI <https://github.com/hpi-swa/smalltalkCI> (great job!). - documented using Pillar <https://github.com/pillar-markup/pillar> (so better!) syntax. Cheers, Alex

About file printOn: method
by stepharo Sept. 11, 2016

Sept. 11, 2016

Hi I will implement the following because this is too annoying. currently 'tmp/foo.txt' asFileReference > File @ tmp/foo.txt and it would be much much better to get back 'tmp/foo.txt' asFileReference So that we can get { 'tmp/foo.txt' asFileReference } > { 'tmp/foo.txt' asFileReference } and not "an Array(File @ tmp/foo.txt)" In addition we should turn the current printOn: method into a displayString method so that a list of fileReference can be well display with File @ tmp/foo.txt for example https://pharo.fogbugz.com/f/cases/18956

Btw here is how the raw data was generated... |classes| outfile := (FileStream newFileNamed: '/tmp/NB-hierarchy3') lineEndConvention: #lf. classes := Smalltalk allClasses select: [ :c | (c name beginsWith: 'NB') ]. classes addAll: (classes flatCollect: [ :c | c allSuperclasses ]) asSet asOrderedCollection. Object printSubclassesOn: outfile level: 1 filter: classes. outfile close. I needed to add printSubclassesOn:level:filter: as a tweak to the existing printSubclassesOn:level:filter: that I thought might be generally useful, so I attached it to an issue... Extend ClassDescription>>printSubclassesOn:level: to have a filter https://pharo.fogbugz.com/default.asp?19077 cheers -ben

linux vm-build
by Nicolai Hess Sept. 11, 2016

Sept. 11, 2016

current linux vm build is broken. the platform display plugin now expects a ioScreenScaleFactor function that isn't defined for vm-display-X11 and vm-display-null and some defines in sq.h had changed from DragLeave to SqDragLeave (and the same for all other drag events). And maybe more, but fixing the above changes, I was at least able to build a vm nicolai

About Year not knowing exact daysInMonth
by stepharo Sept. 10, 2016

Sept. 10, 2016

Hi I started to write a little utility to generate bills. And I need to know the number of days in a month and I was surprised that (Month month: 2) daysInMonth returns 28 because we do not know :) So I thought that I was obviously wrong and I should use (Year year: 2016) daysInMonth > "#(31 28 31 30 31 30 31 31 30 31 30 31)" :( When I look at the implementation this is clear that it is wrong daysInMonths ^ Date daysInMonth totally not aware of the year. I think that daysInMonths should use DateAndTime creating a dummy date for each month and using asMonth daysInMonth (DateAndTime year: 2016 month: 2 day: 3) asMonth daysInMonth > 29 Year >> daysInMonth: aMonthNumber "Returns the days in month for a given month" <expr: #(#(#Year #year: 2016) #daysInMonth: 2) result: 29> ^ (DateAndTime year: self year month: aMonthNumber) asMonth daysInMonth I extended the class with some more practical methods. What do you think? I should push them to pharo? I was surprised that the library was not that good. Stef

Issue validation seems really strange

Hi this is strange because the last issue validation (ilke adding class comments) got such validation output. The errors looks totally strange. Stef

class deprecation notices
by Ben Coman Sept. 10, 2016

Sept. 10, 2016

In Pharo 5.0 I see deprecated classes stripped of all methods and variables defined in a package like... Object subclass: #NBExternalStructure instanceVariableNames: '' classVariableNames: '' package: 'Deprecated50' It was was useful having these remain to facilitate loading Pharo 4.0's TalkFFI for a first look at porting it to Pharo 5.0. Somewhat expectedly, the class initialization fails with... MessageNotUnderstood: CXIdxDeclInfoStruct class>>rebuildFieldAccessors (since that method used to be in NBExternalStructure due to "NBExternalStructure subclass: #CXIdxDeclInfoStruct) But it would be nicer to get a Deprecated message rather than a MNU, initially something simple like this... Deprecated subclass: #NBExternalStructure Deprecated class >> doesNotUnderstand: DeprecatedError signal. but maybe later something like... Deprecated class >> doesNotUnderstand: Transcript crShow: self deprecationNotes. DeprecatedError signal. NBExternalStructure class >> deprecationNotes ^ 'Blah-d-blah. Use UFFIXxxxxx instead'. cheers -ben
